What is margin subscription?

Margin subscription means applying for IPO shares with financing provided by a broker.

Plain meaning

The broker lends part of the application amount and the investor pays capital plus financing cost. The total margin amount is often used as an early demand signal.

Why it matters

Margin oversubscription can show demand before the final public offer result, but it is affected by broker quota, rates, capital cost and market sentiment.

How to read it

Look at the pace of demand, whether broker quota is exhausted, and how the number compares with final public offer oversubscription.

How it appears here

IPO detail pages show estimated margin oversubscription. The allocation tool combines entry fee, capital use and estimated allocation to compare funding efficiency.

Common mistakes

Assuming high margin demand always means a good IPO.
Ignoring financing cost and fees.
Treating margin oversubscription as identical to final public oversubscription.
